Dull in imagery and contrast, DOS Spring comes with a whirl of white water, and riding the crest are boating enthusiasts, shooting the McKenzie River rapids in everything from canoes and kayaks to life-rafts. MLS - Wooden boats and square hull boats making their way down the rapids. MCUS/Rear - People standing at the edge of the shore watching the array of boats go by. MCUS - Two men in a Kayak go by and it looks like they got swallowed by a wave, but didn't. MLS - A rubber raft goes by bouncing up and down.
